ABSTRACT Two new species of Parastrongyloides Morgan, 1928 (Nematoda: Rhabditoidea: Strongyloididae) are described, P. tachyglossi, from the small intestine of the short-beaked echidna, Tachyglossus aculeatus (Shaw, 1792) from southeastern New South Wales and northern Queensland and P. caenolesti from the small intestine of the common grey or dusky shrew opossum, Caenolestes fuliginosus (Tomes, 1863) from Parames du Puruce, the Republic of Colombia. The two new species are distinguished from each other by the position of the two pairs of caudal papillae of P. tachyglossi immediately pre- and post-cloacal in contrast to those in P. caenolesti which are distant from the cloacal aperture and by the generally smaller sizes of males and females of P. caenolesti and the presence of a minute terminal papilla or spine on the tail tip of male P. tachyglossi. They are distinguished from seven of the eight known species of Parastrongyloides by the absence of a single, median, dome-shaped papilla anterior to the cloacal opening in males and by the number and distribution of the other pre- and post-cloacal papillae in the male. The eighth species, Parastrongyloides skrjabini Petrov & Savinov, 1959 has no pre- or post-cloacal papillae. These represent the first species of Parastrongyloides to be described from a monotreme and from a South American marsupial.

副圆线虫属 十一月 (线虫科:Rhabditoidea:Strongyloididae)来自澳大利亚的单孔目动物和哥伦比亚共和国的有袋动物的小肠

摘要 1928 年,描述了来自新南威尔士州东南部和昆士兰州北部短喙针鼹鼠小肠的两种新种的 Parastrongyloides Morgan(线虫纲:Rhabditoidea:Strongyloididae),P. tachyglossi,Tachyglossus aculeatus(Shaw,1792 年) P. caenolesti 来自普通灰色或暗色鼩鼱的小肠,Caenolestes fuliginosus (Tomes, 1863),来自哥伦比亚共和国 Parames du Puruce。这两个新物种的区别在于 P. tachyglossi 的两对尾乳头位于泄殖腔前和泄殖腔后的位置,而 P. caenolesti 的尾乳头远离泄殖腔孔,通常较小P. caenolesti 雄性和雌性的大小以及雄性 P. caenolesti 尾尖上存在微小的末端乳头或棘刺。舌过速。它们与 8 种已知副类圆线虫中的 7 种不同,因为雄性泄殖腔开口前没有一个单一的、正中的、圆顶状的乳头,以及其他泄殖腔前和泄殖腔后乳头的数量和分布。男性。第八种,Parastrongyloides skrjabini Petrov & Savinov, 1959 没有泄殖腔前或泄殖腔后的乳头。这些代表了从单孔目动物和南美有袋动物中描述的第一种副类圆线虫。Savinov, 1959 没有泄殖腔前或泄殖腔后乳头。这些代表了从单孔目动物和南美有袋动物中描述的第一种副类圆线虫。Savinov, 1959 没有泄殖腔前或泄殖腔后乳头。这些代表了从单孔目动物和南美有袋动物中描述的第一种副类圆线虫。
